Sunday showers caused a muddier Lollapalooza this year, and event organizers say the turf took more of a beating than in 2013.

The damage to the sod is worse than last year, when it cost around $300,000 to restore the park, according to Lollapalooza officials. They issued the following statement:

"Due to heavy rains on Sunday, we're seeing more damage to portions of the park than in 2013. We will not know the full extent of the damage until all stages and activations are loaded out, at which point we will do a thorough walk through with the Chicago Park District to assess the damage and create a remediation plan that will leave Grant Park at or better than its pre-festival condition." - Lollapalooza

As in year's past, festival promoter C3 Presents is on the hook for the repairs. In 2011, the company spent more than $1 million to the Chicago Park District to restore Grant Park.

In 2012, the tab was $350,000, about $200,000 more than originally estimated.

Park district officials say C3 has rented Grant Park for the next four or five days, and won't be able to assess the damage and the repair work timeframe until after they're all out.

Sections of the park likely be cordoned off for the rest of the summer in order for the restoration work to be completed, including mulch removal, soil placement and allowing time for the grass to grow again.
